jd kit from a 250 fit a 400

Hi all

I just bought a 99 400f I have a jd kit in my 250 before I sell the 250 I am going to take out the jd needle and put the stock back in does anyone know will these needles work with the 400 if so how should I set them and what needle should I use I am at 7000ft. Thanks

I believe the needles are model specific. For proper jet/needle settings, consult the jetting database...SC
